Make Gregorian dish

[nelson_b]

For me, personally, I like Gregory setup more than usual, cuz it is not ordinary and pretty seldom.

I too like your c.m./fibo hybrid ......... it looks awesome

RimaNTSS, for comparisons, can't you simply remove the sub, and mount or hold the LNB at the ordinary location?
Or is there, then, too much metal in the view / in the way of the LNB?

Of course I can do that @hvdh , but much easier is to remove all Fibo parts, it will probably take about 1 minute. If I make special LNB holder for simple IBU which can be installed also in 1 minute, than 2 tests are possible within relatively small period of time. Maybe I will make such thing in the future.
Here I would like to show how signal from one transponder from 7,3*W changed during last 12 hours. Measured once per minute from 7:39 till 20:00
It is more or less stable, but still we can see some periods when level is down and some periods when it is up. Shortly after 6 PM I was little bit obstructing signal while installing clamp to the feedarm.

Received ball-joints today.... I do not think to install them to antenna, they have too much play in ball-joint. My solution works OK, so will leave it like that. And ball-joints- maybe use them somewhere else some time in the future.

You should have bought some rose joints - there's no play on those at all.

Will keep them in mind.

If you do decide to use Rose Joints make sure you buy some protective rubber boots as well.

I do not know, maybe those Rose Joints can be used for my future PM project?! Will see.

The joints I used to buy (at Uni) where definitely with play in them... but don't remember if there was anything Rosy about them?!?

Yeah - I remember that bit too. The floor often turned very soggy-like when the joints came out. Better wear rubber boots...

@TJExcalibur you were asking something about Gregorian design. Here is a thread I've started long time ago about that.
Just yesterday, friend of mine asked to help mount C-band LNB on his Fibo 120. So, I made this holder, which will stay in place of original Fibo feedhorn. I only do not have 63.5mm clamp and placed 40mm instead.

I will have a look at the drawings I saw somewhere and I believe there is also a Fibo forum. All depends on how much gardening I can avoid in the spring.
